2012 / 61 plate 1.6 petrol ecoboost problems

Hi all,

Having just come back from driving to southern spain, i have a trio of faults that have developed or worsened, and am hoping for a little insight into what the cause is / how critical the issues are.

1. (old issue) when pulling off in first gear, or driving slowly in first gear (think stop start on a motorway), the car will jump out of gear either with a v loud clunk, or with a grrr noise. The solution is to ensure you hold the gear stick and keep it pushed in first gear, which can be a little challenging when starting on a hill etc. it's been like this for a little whils (12 months+) now. i am assuming that this would be a strip down of the gear box or replacement ?

2. knocklng when pulling out sharp left or sharp right - drive shaft related, UJ failing?

3. the most worrying, the is a nasty judder when accelerating under load - seems to be around the 2000-3000 rev mark, accentuated when the car is hot, in all gears. i have read that this could be fuel related (dirty filters, plugs etc), clutch related, or even turbo related. I can only find posts and comments relating to the diesel engine and gear box, nothing for the petrol engine. Has anyone suffered any of these issues, in particular #1 and #3, and most urgently, #3?

Many thanks,

G
